Free Loan Calculator: Calculate EMI, Interest & Repayment Schedule
Before taking any loan, you need to understand the true cost — not just the monthly payment, but the total interest paid over the loan's lifetime. A loan calculator gives you the complete picture: EMI, total repayment amount, and month-by-month amortization schedule.

EMI (Equated Monthly Installment) is calculated using: EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P = principal loan amount, r = monthly interest rate (annual rate / 12), and n = number of monthly installments. This formula ensures each payment covers both interest for that period and a portion of the principal.
Types of Loans You Can Calculate
Home/mortgage loans: typically 15–30 year terms with lower interest rates. Car loans: usually 3–7 years. Personal loans: shorter terms with higher interest rates. Student loans: vary significantly by country and lender. Business loans: range from short-term working capital to long-term capital expenditure loans.
Fixed vs Floating Interest Rates
Fixed rate: your EMI stays the same throughout the loan term — predictable but usually slightly higher. Floating rate: your EMI changes based on benchmark rates (like RBI repo rate in India, or Fed funds rate in the US). Floating rates are typically lower initially but carry interest rate risk.

Reading the Amortization Schedule
An amortization schedule shows each monthly payment broken down into principal and interest portions. In the early months, most of your payment goes toward interest. As you pay down the principal, the interest portion decreases and the principal portion increases. Formly's calculator generates a full month-by-month schedule.
Impact of Prepayment
Making a lump-sum prepayment reduces the principal, which dramatically reduces total interest paid. For example, on a $300,000 mortgage at 7% over 30 years, a $10,000 prepayment in year 1 can save $25,000+ in interest over the loan's life. The calculator lets you model prepayment scenarios.
Loan Calculators for Different Countries
Loan calculations use the same mathematical formula globally, but tax implications differ. In India, home loan interest is tax-deductible under Section 24. In the US, mortgage interest may be deductible if you itemize deductions. In the UK, mortgage interest relief was phased out for residential landlords. The calculator shows raw financial figures — consult a tax advisor for local tax implications.
